The invention now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This invention may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In the disclosure, when an element (or an area, a layer, a portion, etc.) is referred to as being “on,” “connected to,” or “coupled to” another element, it means that the element may be directly connected to/coupled to the other element, or that a third element may be disposed therebetween.

Like reference numerals refer to like elements. Also, in the drawings, the thickness, the ratio, and the dimensions of elements are exaggerated for an effective description of technical contents.

It will be understood that, although the terms “first,” “second,” etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element may be referred to as a second element, and a second element may also be referred to as a first element in a similar manner without departing from the teachings herein.

In addition, terms such as “below,” “lower,” “above,” “upper,” and the like are used to describe the relationship of components shown in the drawings. The terms are used as a relative concept and are described with reference to the direction indicated in the drawings.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, “a”, “an,” “the,” and “at least one” do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. For example, “an element” has the same meaning as “at least one element,” unless the context clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.” “Or” means “and/or.” As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.

In the disclosure, being “directly disposed” may mean that there is no layer, film, region, plate, or the like added between a portion of a layer, a film, a region, a plate, or the like and other portions. For example, being “directly disposed” may mean being disposed without additional members such as an adhesive member between two layers or two members.

“About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” can mean within one or more standard deviations, or within ±30%, 20%, 10% or 5% of the stated value.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It is also to be understood that terms such as terms defined in commonly used dictionaries should be interpreted as having meanings consistent with the meanings in the context of the related art, and should not be interpreted in too ideal a sense or an overly formal sense unless expressly so defined herein.

Embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.

The resolution of the pixel circuits of the first partial region Pis higher than the resolution of the pixel circuits of a corresponding region in the first display region DA. That is, pixel circuits are more densely disposed in the first partial region Pthan in the first display region DA. More specifically, the number of pixel circuits disposed per reference area in the first partial region Pmay be greater than the number of pixel circuits disposed per reference area in the first display region DA. Into, a reference area may be, for example, an area in a rectangular shape including two adjacent light emitting elements along the second direction DR.

However, an area occupied by one fifth pixel circuit PC, an area occupied by one first pixel circuit PC, and an area occupied by one second pixel circuit PCmay be substantially the same as each other. When pixel circuits have a same area as each other, it means that the pixel circuits have a same layout structure, and it means that transistors constituting a pixel circuit have a same size as each other and are arranged in a same arrangement rule as each other. In the disclosure, “substantially the same” means not only that numerical values such as an area are physically the same, but also means that the numerical values are in the same range considering differences within an error range that may occur in a process despite the same design. In an embodiment, since the fifth pixel circuit PC, the first pixel circuit PC, and the second pixel circuit PChave a same area as each other, it is possible to design a uniform circuit. Since noise factors, such as a peripheral signal and parasitic capacitance, which affect the operation of the fifth pixel circuit PC, the first pixel circuit PC, and the second pixel circuit PCmay be the same as each other, the control of a pixel circuit may be easy.
